1 Claim. (Cl. 126-595) This invention relates to heat providing elements for tobacco curing barns and other enclosures and in particular a burner housing mounted in one end of a header with deflecting baflles adjustably mounted above the burner housing and adjoining section of the header.

The purpose of this invention is to provide an adjustable deflecting element above a heat supplying unit whereby heat traveling upwardly from the unit may be deflected to diflferent sections of an enclosure in which the device is positioned.

Various attempts have been made to evenly distribute heat throughout the interior of a tobacco barn, and at the same time provide suflicient circulation for curing tobacco, however, it is diflicult to incorporate a burner, and particularly an oil burner in a heating system without heat being concentrated in an area around the burner. With this thought in mind this invention contemplates a burner unit having deflecting baffles adjustably mounted in the path of air traveling upwardly therefrom whereby the heated air is directed to dilferent sections of an enclosure in which the device is positioned.

The object of this invention is, therefore, to provide means for mounting deflecting baflles above a heating unit whereby the position of the baflles is readily adjustable and whereby heat from the unit may be directed to one section of an enclosure for a certain period of time, and to different sections for following periods of time.

Another object of the invention is to provide a heating unit with deflecting baflies adjustably mounted thereon in which the unit may readily be installed in one end of a header in a tobacco barn or the like.

A further object of the invention is to provide a heating unit having deflecting baffles adjustably mounted thereon for use in tobacco curing, in which the unit is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a housing having an oil burner with a down draft flue extended therefrom and havinga deflecting baflie carried by the upper surface, and an additional deflecting bafile with means for mounting the said additional deflecting baflle on an adjoining section of a header to which the burner housing is connected.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure l is a plan view of the improved heating unit with part of a buflle over the burner housing broken away.

Figure 2 is a side elevational view of the unit shown in Fig. 1 showing the deflecting baflies in horizontal positions in full lines and in inclined positions in dotted lines.

Figure 3 is a cross section through the header, looking toward the heating unit and showing the battle carried by the header in a horizontal position in full lines and in inclined positions in dotted lines.

Figure 4 is a longitudinal section through the burner housing showing the housing attached to an end of a Patented Sept. 11, 1956 header with parts broken away, said section being taken on line 4-4 of Fig. 1.

Figure 5 is a plan view showing the burner on an enlarged scale, the base of the housing being broken away.

Figure 6 is a detail showing the fuel disc of the burner. Referring now to the drawings wherein like reference characters denote corresponding parts the improved to bacco curing oil burner of'this invention includes a down draft oil burner having a cup shaped casing 10 with a fuel disc 11 therein positioned below a down draft flue 12 and mounted ina well 13 on a base 14 of a housing having side walls 15 and 16, end walls 17 and'18 and a cover 19, and the housing which is provided with a deflector 20 is mounted in the end of a header 21 above which a baflle 22, mounted on a shaft 23, is supported with legs 24 and 25. The header 21 is adapted to extend to a stack or chimney whereby the circulation of air upwardly through the stack pulls air downwardly through the flue 12.

As illustrated in Fig. 4 the base 14, which is supported on legs 26 is provided with an annular boss 27 in which the well 13 is positioned and the casing 10, which is located in the well is provided with a frustro conical shaped inner surface 28. The upper edge of the wall of the casing 10 is provided with an annular groove 29 in which overflow fuel may accumulate and fuel from the groove 29 is returned to the supply through a passage 30 which extends to a return tube 31. The tube 31 is threaded into the lower end of the casing 10 and a fuel supply tube 32 which is positioned in the center of the base 14, is also threaded into the lower end of the casing 10.

The fuel disc 11 is provided with spaced radially disposed notches 33 and, as shown in Fig. 4, the edge of the disc is beveled to correspond with the taper of the inner surface 28 of the casing 10 whereby the disc rests against the inner surface, as shown in Fig. 4.

The down draft flue 12, which is positioned in an opening 34 in the cover 19 of the housing is supported by an adjusting screw 35 that is threaded in a cross bar 36, and with the lower end of the adjusting screw resting upon the upper surface of the disc 11 the elevation of the lower end of the down draft flue 12 is adjustable in relation to the upper edge of the burner casing. The cover 19 is provided with an opening 37 in which a cover plate 38 having a handle 39 is positioned.

The deflector 20 is connected by hinges 40 to a horizontal section 41 of a rod supported above the housing of the burner with arms 42 and 43. The opposite end of the deflector 20 rests upon a similar rod 44 which is also supported above the cover 19 with arms 45 similar to the arms 42 and 43. The cover 19 is secured to the housing with bolts or screws, as indicated by the numeral 46.

The end wall 18 of the burner housing is provided with an annular flange 47 that extends around an opening 48 and, as illustrated in Fig. 4, the end of the header 21 is positioned over the flange 47 whereby heat from the burner housing passes directly into the header.

The lower ends of the legs 24 and 25 that support the bafile 22 are secured by bolts 49 and 50 between flanges forming the ends of bands 51 and 52 which extend around the outer surface of the header 21.

The upper ends of the legs 24 and 25 are provided with hubs 53 and 54 in which the ends of the shaft 23 of the bafi le 22 are clamped with hand screws 55 and 56 whereby the baffle may be clamped in adjusted positions as indicated by the dotted lines in Fig. 3. The legs 24 and 25 are provided with openings as indicated by the numeral 57 in which one end of the shaft 23 may be positioned when it is desired to adjust the baffle to an inclined position such as indicated by the dotted lines in Fig. 2. It will be noted that the ends of the shaft 23 extend beyond 9. hubs. i and 5.4, to. provide. sufficient length so thatone end of the shaft may beheld in one of the hubs with the opposite end in one of the openings 57.

The baffle 22; is;alsotproyided; with attransuersely dis-- posed plate 58 which, with the baflleadjusted tothe position of the dotted lines; sloping downwardlytoward the burner housing, prevents; thetobacco sliding from the bathe-to the burner housing.

With: the parts. arranged in, this. manner the. header 21 may extend from? the; burner housing to a remote point such as throughout thelowen-partofia tobacco barnor the like, or, the header'2 ..mey' be; attached to an elongated header asindieated. by; the numeral: 59.; The. headers 21 andSSsarepositioned in heformtofarectangle witltport-ions thel eof; spacedzfromthe side and one endiof a tobaceo; harm and with the header extending from the lions ing; around the cup-shaped burner. element 10 to a stack or the like: thepull; resul'tingfmm the draft of the stack circulates air through. the header- 59., thereby drawing the airdownwardly through1theflue-12 whereby heated air is supplied to the. burner inthe cup-shaped casing: 10-.
